Re: Restored 2-4-4-2

Use little engines or RRSC 0-4-0 parts that way you have piston valves and outside VG.

Re: Building the 2.5" Scale Shay

Curious how thick the insulation is on your boiler? I saw you used 1/8 thick material but assume you likely made a few wraps around with it.

Re: Air Compressor control

With Tristan's idea, you could use non scale off the shelf components and hide them somewhere, perhaps in the cab or under the cab. Anyone built something like this?

Might also have to adjust the thickness of the front bolster where the lead truck mounts, possibly remove shims or slightly machine it to let the lead truck carry less weight. And/Or remove leafs from the front truck suspension to make it less firm. Also, possibly adjust the elevation of the swivels...
